10" Big Blue Specialist Filter (Nitrate and Nitrite Removal)
In stock
It is most commonly used by fishkeepers as nitrates/nitrites in the water can present major problems for the growth and reproduction of the fish.
The life of this cartridge is proportional to nitrate levels and usage - however - testing the efficiency of this system (i.e. to check the cartridge) can be easily achieved using over the counter test.
Important Note
The life of the filter is proportional to the loading of Nitrate (NO3) and Sulphate (SO4) in the source water and the volume of water used. The more Nitrate and Sulphate in the source water and the more water you use, the faster the filter will exhaust.
